Consider the following options instead:\r\n\r\n  - reading the Python tutorial: https://docs.python.org/3/tutorial/\r\n  - posting in the \"Users\" category on discuss.python.org: https://discuss.python.org/c/users/7\r\n  - emailing the Python-list mailing list: https://mail.python.org/mailman/listinfo/python-list\r\n  - searching our issue tracker (https://github.com/python/cpython/issues) to see if\r\n    your problem has already been reported\r\n--\u003e\r\n\r\n# Bug report\r\n\r\nAccording to documentation all calls to ZoneInfo should raise `ValueError` or `ZoneInfoNotFoundError`. \r\nCreating a ZoneInfo object with an invalid very long timezone (length \u003e 255) an OSError is raised instead (`OSError: [Errno 36] File name too long`). \r\n\r\nI believe that https://github.com/python/cpython/blob/29f1b0bb1ff73dcc28f0ca7e11794141b6de58c9/Lib/zoneinfo/_common.py#L11-L24 should also handle the `OSError` exception raised by open and reraise it to `ZoneInfoNotFoundError`.\r\n\r\nSample code for reproduction:\r\n```\r\nfrom zoneinfo import ZoneInfo\r\nZoneInfo(\"a\"*256)\r\n```\r\n\r\n# Your environment\r\n\r\n\u003c!-- Include as many relevant details as possible about the environment you experienced the bug in --\u003e\r\n\r\n- CPython versions tested on: Python 3.10.4\r\n- Operating system and architecture: Debian GNU/Linux 11 (bullseye)\r\n\r\n\u003c!--\r\nYou can freely edit this text.
